I've had a yeast infection right before my period and I ended my period last night and I'm afraid it came back but I'm not sure. I don't itch badly or burn. Sort of uncomfortable but not seriously uncomfortable. Want to know what's going on but terrified of the gyno.just want to know what's going on before I try the gyno

Unfortunately, being on the internet and all we can't tell what's wrong with you without a physical exam. So, if you're really concerned you need to go back to the doctor and perhaps get a different medication to treat your yeast infection or figure out if something else is wrong.
There is also the possibility of trying an over the counter yeast detection kit which you can find at most pharmacies. But ultimately, you'll probably have to see your doctor, particularly if it's a recurrence of the same yeast infection you had previously which would require a stronger medication to treat (assuming you went to the doctor for the first one).
